SOIL-STACK CONNECTION.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed April 16, 1912. Serial No. 691,176.

To all whom it may concern 7 Be it known that I, RICHARD J. SoHwEirzen, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soil-Stack Con:

I nect-ions, of which the following is a specification.

The present invention relates to a form of pipe used for the purpose of connecting a toilet fixture with a soil-stack, and said connection is of a form to enable a sealed joint the pipe as to obtain the same cross-sectional area throughout the interior bore thereof.-

A further object of the invention is to render the connection adjustable as to length, and to so arrange the chamber which receives the sealing substance as to enable the sealing substance to act as a cementative to adhere the pipe and connection together.

The invention further consists in the features of construction and in the combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal section of the connection, of the present invention in operative position; Fig. 2, a

if sectional detail of the thimble of the present invention; Fig. 3, a view showing the pipe and thimble in engagement, with the pipe tilted at an angle; Fig. 4:, an elevation of the connecting pipe of the present invention; Fig. 5, a plan view of said pipe; Fig. 6, a section on line 66 of Fig. 5, lookin in the direction of the arrow; and'Fig. a detail of the connection between the thimble and fixture.

In the art to which the present invention relates, it is necessary to form a calked joint or sealed connection at the juncture of the connecting pipe leading from the soil-stack and the toilet fixture. This is to prevent. the escapement of gas or liquid at the juncture of said connecting pipe and fixture. .It is considered more expedient in practice to form this calked joint prior to the installation of the fixture, in order to determine more accurately whether the joint is sufficiently gas and water tight.

Itis one of the objects of the present invention to so arrange the well which receives the sealing substance that it will be possible for the mechanic to calk this joint prior to the installation of the fixture; that is, he can first set what may be termed the foundat'ion for the fixture, and then perform the calking operation necessary to make the tight joint between this foundation and the fixture. And he can further easily determine before setting the fixture whether the seal is perfect or not by reason of the fact that it is fully visible while being formed. A further diificulty which is experienced in the connecting of fixtures to soil-stacks lies in the fact that in some .instances a relatively shallow space is provided between the floor and the ceiling, and the pipe connecting the soil-stack and the fixture therefore must lie, when inserted, relatively close to the floor line in order to accommodate itself within the space allowed. The device of the present invention is designed with a viewto overcoming these difliculties, and in the form shown in the drawings is as follows:

Referring particularly to Fig. 1, the de' vice is illustrated as consisting of a pipe 8, which is of elbow formation, and terminates at one end in a relatively short upwardly extending neck 9. At the point where the neck and body of the pipe come together, said pipe has its upper wall depressed as in dicated at 10. By this arrangement, the upper end of the neck lies in close relation to the upper surface of the pipe 8, reducing the transverse dimension of the joined pipe and neck and enabling the pipe to be positioned in a shallow space, and at the same time giving the desired length to the neck. By this arrangement should the system be installed in a building where the space between the fioor and the ceiling beneath is shallow, no difliculty will be experienced in installing the pipes in this space, by reason of its compact formation. By depressing the pipe as indicated at thepoint 10, the di mensions of the pipe will. be contracted in one direction atthis point. It is not desir able to have a contraction of this nature, which will restrict the areaof the pipe at this point, as such a restriction would tend to increase the danger of the pipe choking if an unusualheavy flow. were passed therethrough, Therefore, in order to maintain the same cross-sectional area throughout the pipe and prevent such a point of congestion, the pipe is broadened out at the sides thereof, as indicated by the numeral 11. in Figs. 5 and (3, which counteracts the contraction caused by the indenting of the upper wall.

Adjacent to the point where the neck and body of the pipe meet, a screw-thread 12 is cast upon the outer surface of said neck. This thread is adapted to receive and mesh with a cast thread 13 formed on the inner face of the lower end of a collar 14. Said collar is provided with a flange 15 adapted to rest upon the upper face of the flooring which is indicated by the numeral 16. The flange is provided with a series of radial slots 17, which receive locking members 18,

' which serve to join said collar to a fixture 19 in a manner clearly understood by referring to Fig. 7.

The provision of the cast threads 12 and 13 enables many desirable functions to be accomplished: It permits of an adjustment of the collar 14 with respect to the floor line, so that said collar can be positioned to rest squarely and securely upon the floor, irrespective of the position of the pipe 8 below the floor. Furthermore, the threads act as spacing members to separate the inner wall of the collar away from the outer wall of the neck for the entire distance above the termination of the screw-threads, where these surfaces are adjoining. This provides a chamber 20 between the pipe and thimble, into which suitable sealing substance 21 can be tamped. Such sealing substance acts as a preventive against leakage of gas or other substance at the point of connection of the neck and collar, and further serves as a cementative agency for joining the collar and neck together in a secure and staple manner.

By utilizing cast threads, a considerable amount of play is allowed between the mesh ing threaded surfaces, which permits the flange of the collar to adjust itself to lie tiat upon the floor in case the pipe is not extending parallel with the floor. This feature will be clearly understood from a study of Fig. 3 And the character of said threads also allows the sealing substance to filter or work its way in between the meshing portions of the thim'ble and pipe, effecting the cementing action above referred to. By connecting the thimble and pipe in this manner, said connection can be made and the sealing substance placed in the chamber 20 prior to the setting of the fixture. This allows the tamping operation to be easily and readily accomplished, since the chamber 20 is readily accessible to the workmen, inasmuch as itis brought very close to the floor line. This is a very desirable feature inQdevices of this kinohsince. it enables the seal to be moreeasily andeificiently made, and also enables the workman to see the nature of the seal which has been produced, so that he can determine whether or not it is a good one. If the seal is made under conditions where it cannot be observed in the process of formation, bubbles and other deformities are sometimes present and pass unnoticed, but which later render the seal defective and permit the escapement of when the system is put into operation.

The device of the present invention is extremely cheap and simple of construction, consisting as it does solely of two parts: the pipe with the neck joined thereto, and the thimble. All portions of the device are produced by a casting operation and no machine work of any kind or description is necessary to produce the completed article, ready for use. The upper end of the thimble is provided with a concave flange 22, which receives a ring of packing material 23 that forms an additional preventive against the escapement of gas around the floor line and around the juncture of the pipe and thimblc. The flange 22 is, however, of a relatively shallow nature, so as not to block or cover the entrance to the chamber 20. The outlet- 23 from the fixture extends below the upper edge of the neck, so that a continuous and unbroken. passage for fluid is provided.

As shown in Figs. 1 and 3, the neck of the pipe 8 is provided with an interior thread 25, which is adapted to receive a plug 26. These features provide means whereby the system can be tested prior to the installation of the fixture. That is, by inserting the plug in the manner shown in Fig. 3, a volume of water can be passed through the piping to determine the effectiveness of the connectio-ns, the plug acting as a means to prevent the water from squirting through the open end of the neck.

By the arrangement of cast threads shown and described, a relatively long seal can be produced at the juncture of the pipe and thimble, thus forming an efiicient preventive against the escapement of gas at this point.
